In my mind you are essentially asking "which hormone creates a greater physically ability" that is why you selected men and navy SEALS not individual emotional strength.
If you want to talk opinion sure discuss more human attributes that vary like emotional toughness and drive to succeed.
well, that's actually why I picked to use the navy seal/special op scenario.
their training is not just about physical strength... emotional toughness, and drive to succeed are greatly weighed.
their training is designed to say hey... when you're at your limit with your physical strength.... dig deep and push passed what you
think you can't.... find the mental toughness to drive through the little thing in your head saying you can't take anymore, because you can.
I mean, you gave an example of body builders increasing testosterone... if anything I would associate that with being nothing related to emotional toughness and drive to succeed, as you stated I must use to weigh my option.
And as far as me getting "defensive", as such said by two of you.... there's 2 pages of responses on here that greatly weigh in on other peoples' person opinions, but shit... the second I said something, I was instantly bombarded one right after the other of how I am wrong, or how my opinion sucsk. Don't get it. It's matter of opinion.
